Description

Upstream water quality management and pollution response system

The present invention uses a siphon principle to discharge the water in the upstream stream to the downstream without excessive energy consumption, thereby managing the upstream water quality, and monitoring the compensation stream by section to provide an immediate response to the inflow of pollutants. About.

This is to keep and control a certain amount of water by blocking the flow of water, and it functions to temporarily store water flowing from the upstream. However, these underwater beams have a problem in that soil, various organic matters, garbage, etc. introduced from the upper stream are clogged and settled in the underwater beam, accumulating and rot. Accordingly, the amount of dissolved oxygen in the upstream water blocked by the underwater beam decreases as it goes deeper, and the water is stagnant and green algae is generated, causing water pollution in rivers and rivers and destruction of environmental ecosystems.

Conventionally, in order to solve such a problem, "underwater beams in which a guide pipe is installed (Korean Patent Laid-Open Publication No. 1994-0018527)" or "underwater beams that do not accumulate sediments (Korean Utility Model Publication 1995-0033385)" have been derived. However, in the case of the "underwater beam with an induction pipe", sediment accumulates between the guide tube and the guide tube and is not discharged downstream, and the guide tube is blocked by the sediment and does not function properly. In the case of "stacking underwater beam", a number of holes are drilled in the lower part of the underwater beam to allow water to flow. In this case, the sediment is discharged through the hole, but there is a problem that the water, which is the original function of the underwater beam, cannot be properly maintained.

On the other hand, the principle of a siphon in which a liquid in a high place is lifted up and moved to a low place without tilting or moving a container has been variously applied in real life. Registered Patent 10-1532276 "Prevention of green algae in the compensation stream and sludge discharging system" applies this siphon principle to prevent the occurrence of green algae due to water stagnation and pollution of the water quality by allowing the water in the compensation stream to flow downstream without requiring energy. According to the arrangement of pipes and auxiliary branch pipes, the sediment (sludge) on the upper stream floor is inhaled and discharged as a whole to obtain the effect of cleaning and dredging.

Recently, the problem of water decaying due to the beams installed by the Four Rivers Project has emerged, and the question of whether the beams should be demolished has emerged as a social issue. However, in terms of efficient management of water resources, there is clearly a net function of beams, and since the cost of removing the already installed beams is large, it is more reasonable to think about a way to efficiently manage water quality without requiring excessive energy.

The present invention is provided in a beam installed in a river, such as a river or a river. Normally, the water in the deep upstream of the river is stagnant based on the beam, and the amount of dissolved oxygen decreases as it goes down to the deep.

The present invention induces the circulation of water between the surface layer and the deep layer by discharging the water in the depth of the upper stream by siphoning, and protects the ecosystem by increasing the concentration of dissolved oxygen in the deep layer, and also protects the ecosystem by increasing the concentration of dissolved oxygen in the upper stream. It is to obtain the effect of cleaning and dredging by discharging it to the downstream side together with the water in the depth.

In addition, the present invention divides the upstream of the compensation stream, monitors the level of contamination for each section at all times, and prevents overall contamination upstream by discharging the water in the section with high contamination levels to the downstream, and promptly responding to the pollutant source. It is to make this happen.

Hereinafter, the present invention will be described in detail together with the accompanying drawings.

The present invention "beams 110 installed to partition the upstream and downstream across the river; A depression 120 formed below the downstream surface of the beam 110 to be lower than the upstream floor; It is connected along the bottom of the upper stream of the river and crosses the beam 110 and is piped to reach the indentation 120, and the outlet 10 is disposed in the indentation 120, and the water supply pump 30 is coupled.

It provides a compensation stream water quality management and pollution response system 100", characterized in that it is configured to include, and is configured to control the driving of the roller 164 in the management unit 150.

[Fig. 1] and [Fig. 2] are a side cross-sectional view and a plan view of an embodiment of a water quality management and pollution response system 100 in the upper stream provided by the present invention.

The siphon principle is useful when moving water from high places to low places without applying power. Therefore, to move the water of the upstream floor (deep water) to the downstream based on the beam, the downstream floor must be lower than the upstream floor.

Since the bottom of the river is made of a continuous surface, in the present invention, a depression 120 is formed below the downstream surface of the beam 110 than the upstream bottom. The concave portion 120 may be formed to be recessed from the bottom surface around the point where the outlet 10 of the flow path pipe 130 is directed, as shown in [Fig. 2], and the downstream surface of the beam 110 Accordingly, it may be formed in the form of a horizontally long trench.

In addition, the flow pipe 130 to which the water feed pump 30 is coupled is piped in the pipe so that it extends along the bottom of the upper stream of the river and crosses the beam 110 to reach the concave portion 120, and the outlet 10 Is disposed in the concave portion 120, and a plurality of branch pipes 140 having a suction port 20 formed at an end thereof are coupled to communicate with the flow path pipe 130.

Accordingly, water introduced into the suction port 20 by a siphon principle is discharged to the concave portion 120 through the outlet 10 through the branch pipe 140 and the flow path pipe 130. In addition, as shown in FIG. 2, the branch pipe 140 may be configured to communicate with the auxiliary branch pipe 145, and a suction port may be formed in the flow path pipe 130 as well.

According to the pipes of the branch pipe 140 and the auxiliary branch pipe 145, it may be configured to evenly suck water from the bottom of the river stream, thereby obtaining the effect of cleaning and dredging through sediment suction-discharge.

In addition, the flow pipe 130, the branch pipe 140, and the auxiliary branch pipe 145 are provided with an on/off valve 40 where necessary to control the water flow of the entire flow pipe 130 or a partial branch pipe 140 Or it is possible to adjust the local water flow such as the end of the auxiliary branch pipe 145. In addition, by installing and controlling the on-off valve 40, it is possible to control the flow of water in whole and in part.

Through the above configuration, water in several sections of the upper beam can be discharged over the beam to the downstream of the beam without applying additional power. However, in order to implement the siphon principle, water must be filled in the flow path pipe 130, and thus the water feed pump 30 may be driven as necessary to meet such conditions.

By coupling the water feed pump 170 to the flow path pipe 130, when the siphon operation is not possible due to a low upstream water level, the water feed pump 170 may be operated to artificially cause a siphon operation. That is, it is possible to prevent shooting by giving a flow to stagnant water during the dry season, and the flow rate can be adjusted with the on/off valve 40, and the operation of the water feed pump 170 can be stopped when the siphon operation proceeds.

Due to the formation of the concave portion 120 and the arrangement of the flow path pipe 130 and the branch pipe 140 as described above, the water in the free oxygen state at the bottom of the compensation stream is discharged to the downstream, and the amount of dissolved oxygen increases in the deep upstream. It will be possible to protect the ecosystem. In addition, the elution of nutrients is suppressed (anaerobic decomposition is suppressed) due to an increase in the amount of dissolved oxygen in the deep upstream part, and as a result, the occurrence of green algae is suppressed.

However, by coupling the on/off valve 40 to the flow path pipe 130 in order not to lose the original function of the beam, it is possible to control the movement of water and adjust the water level upstream.

In the present invention, the operation of the water feed pump 30 and the on/off valve 40 is configured to be integrated and controlled by a separate management unit 150.

The management unit 150 is a computer system configured to monitor the water quality of each section of the compensation stream and respond appropriately according to the degree of pollution, and the pollution detection sensor 50 installed around the branch pipe 140 inlet 20 The sensing information is collected and analyzed, and the operation of the water feed pump 30 and the opening/closing valve 40 is controlled according to the analysis result.

The upstream can be monitored by dividing it into multiple sections, and it can be specifically divided around a sewage outlet.

One or more branch pipes (including'auxiliary branch pipe', hereinafter the same) are piped for each divided section, and a pollution detection sensor around the inlet 20 of the branch pipe 140 as shown in [Fig. 3] By installing (50), it is possible to configure the water quality of the Bosang Stream to be monitored for each section and to take active measures according to the pollution level.

For water quality by section of the upper stream, hydrogen ion concentration (pH), biochemical oxygen demand (BOD, mg/ℓ), chemical oxygen demand (COD, mg/ℓ), total organic carbon (TOC, mg/ℓ), suspended matter Monitor mass (SS, mg/ℓ), dissolved oxygen (DO, mg/ℓ), total phosphorus (TP, mg/ℓ), total nitrogen (TN) (mg/ℓ), and ecological toxicity (TU) as factors Therefore, the contamination detection sensor 50 is configured to sense all or part of the factor, and continuously transmits real-time sensing information for each factor, or when a value equal to or greater than a threshold set for a specific factor is sensed, the corresponding sensing information Can be configured to send out only.

Based on the sensing information collected from the pollution detection sensor 50, the management unit 150 opens the opening/closing valve 40 of the branch pipe 140 disposed in the section where the pollution degree is evaluated highest, and the remaining branch pipe 140 By controlling the on/off valve 40 to be closed, it can be configured so that the water in the section with high pollution degree is preferentially drained before diffusion in the compensation stream. The management unit 150 may set an opening time of the on/off valve 40 and an opening/closing control cycle of the on/off valve 40. [Fig. 4] is a schematic diagram of an operation relationship between the management unit 150, the contamination detection sensor 50, and the on/off valve 40.

The management unit 150 assigns a preset weight for each sensing factor from the collected sensing information for each section, converts the index score, and sorts the pollution level according to the summed value, or sets the importance level for each sensing factor to detect the sensing value of the priority factor ( In the case of the operation rate of the priority factor, a method of sorting the pollution level according to the sensing value of the next factor) can be taken.

In addition, the management unit 150 may collect sensing information for each section and accumulate and utilize it as big data. In other words, preliminary measures are taken in the section where the pollution level is expected to increase according to the analysis of the pattern of sensing information for each section, or for the section where the sensing information for each section is out of the normal pattern and the level of contamination is rapidly increased, an epidemiological investigation is concentrated on the section to determine the cause of contamination early Can be found and taken into account.

On the other hand, by helically coupling the screw blades 21 whose height increases along the inner circumferential surface of the suction port 20 in a spiral manner, a vortex may be generated around the suction port 20. [Fig. 5] shows a state in which the screw blades 21 are coupled to the inner circumferential surface of the suction port 20.

The height of the screw blade 21 is configured to increase gradually from the suction port 20 to the inside, so that the inflow of water is not obstructed by the screw blade 21, and as the water enters the suction port 20, the screw A flow rotating along the blades 21 is generated. In this way, the inside of the branch pipe 140 or the flow path pipe 130 may be washed by the rotating flow of water.

In addition, a flow of water rotating around the suction port 20 is generated, and accordingly, a local flow is generated in the deep upstream portion, and a sediment in the form of sludge may float.

By bending the suction port 20 upward or downward according to the state of the upstream floor of the beam 110, it is possible to induce the generation of vortex around the suction port 20 and suction of the sediment more efficiently.

A sieve 22 is coupled to the suction port 20 as shown in [Fig. 6], so that a relatively large object such as a stone or a piece of wood is caught in the tube according to the size of the sieve 22, or a fish Small animals such as the back can be prevented from being sucked into the suction port 20 and only sludge such as mud can be sucked and discharged.

[Fig. 7] shows an embodiment in which the suction port 20 is inserted and fixed in the inner space 24 of the gaebion 23. The inner space 24 facilitates the fluidity of fine pollutants introduced between the gasbion net and the gravel filter, thereby smoothly inhaling and discharging the fine pollutants. In this case, while negative pressure is applied to the inner space 24 of the gabion 23, water and sludge are introduced through the inlet 20 through the gap between the stones constituting the gabion 23, and a relatively bulky stone, Inflow of wood chips, fish, etc. is blocked from the outer wall of the gabion 23 (see (a) of [Fig. 7]). In addition to the suction port 20, a plurality of suction holes are formed in the pipe line inserted into the gasbion 23 among the flow pipe 130 or the branch pipe 140 so that smooth suction-discharge of the compensation stream water and sludge is achieved. I can.

The gaebion 23 may be configured such that the upper part rises above the water surface, and the upper surface is opened as shown in (a) of [Fig. 8], or the upper surface as shown in (b) of [Fig. 8] Internal management can be achieved by installing an opening and closing door.

In addition, as shown in [Fig. 9], by attaching the on-off valve 40 to the upstream section and the downstream section of the flow path pipe 130, respectively, and by coupling the supplementary water pipe 180 to the flow path pipe 130 , It is possible to solve a problem when air enters the flow path pipe 130 or a siphon operation is not performed due to a low upstream water level.

The make-up water pipe 180 is a pipe branched between the on-off valves 40 of the flow pipe 130 and open to the atmosphere, and the injection valve 181 is coupled to the make-up water pipe 180. A funnel-shaped replenishment water injection unit 182 extending upwardly as shown in [Fig. 8] is coupled to the upper end of the replenishment water pipe 180, thereby increasing the convenience and efficiency of the replenishment water injection operation.

This configuration is a configuration for generating a siphon action without power, closing all the on-off valves 40 mounted in the upstream section and the downstream section of the flow path pipe 130, and opening the injection valve 181 to inject water. (At this time, the air filled in the flow path pipe 130 is discharged through the supplementary water pipe 180), and after closing the injection valve 181, all the opening/closing valves 40 are opened so that the siphoning action is performed without power. Let it happen.

In addition, as shown in [Fig. 10], the on-off valve 40 is mounted in the upstream section and the downstream section of the flow path pipe 130, respectively, and a supplemental water pipe between the on/off valve 40 of the flow path pipe 130 Combining 180 is the same as in the above-described embodiment. However, the air pipe 190 must be additionally coupled to the flow pipe 130, and the supplementary water pipe 180 must extend upstream of the river, and a make-up water pump 185 capable of raising water to the make-up water pipe 180. The difference is that) must be combined. The air pipe 190 is also a pipe branched between the on-off valve 40 of the flow pipe 130 and opened to the atmosphere, and an air discharge valve 195 is coupled to the air pipe 190.

With this configuration, all the on-off valves 40 mounted in the upstream section and the downstream section of the flow path pipe 130 are closed, and the air discharge valve 195 is opened, and the make-up water pump 185 is opened. After driving to inject water upstream of the river into the flow pipe 130 (at this time, the air filled in the flow pipe 130 is discharged through the air pipe 190), the air discharge valve 195 is closed. , By opening all the opening and closing valves 40 so that the siphon action occurs without power.

On the other hand, as shown in [Fig. 11], by combining the hydroelectric power generation device 200 in the downstream section of the flow pipe 130, power generation by water falling along the flow pipe 130 can be achieved. have.

In addition, the present invention may further include an opening/closing facility 180 installed on all or a part of the bent portion 60 formed according to the arrangement state of the flow path pipe 130 and the branch pipe 140. Since sludge may accumulate in the bent part 60, the opening and closing facility 180 is opened to allow water to flow into the open portion, thereby preventing the sludge accumulated in the flow path pipe 130 and the branch pipe 140. To be discharged.

The opening and closing facility 160 may be configured in various ways, and in the present invention, specifically, one or a plurality of through holes 161 formed in the front or rear of the bent portion 60 as shown in [Fig. 12]; An exterior 162 covering the through hole 161; A roller 164 coupled to the outside of the exterior 162; And a rail (164) providing a ground plane of the roller (183). It provides an embodiment of the opening and closing facility 160 configured, including.

By controlling the driving of the rollers 164 in the management unit 150, when the outer surface 162 is moved forward and backward, and the through hole 161 is opened by the movement of the outer surface 162, the When water is sucked through the through hole 161 and discharged through the discharge port 10, the precipitate of the bent part 60 is discharged together.

In addition, as shown in [Fig. 13], a screw blade 21 is mounted inside the flow path pipe 130 or branch pipe 140 to induce a rotational flow in the pipeline, and a river using the rotational flow generated accordingly You can make the water circulate.

That is, the propeller 25 in the pipe is mounted in the section in which the rotational flow is induced (rotation current induction section), and the rotational motion of the propeller 25 in the pipe is transmitted to the outside of the flow path pipe 130 or branch pipe 140. By installing the rotating outside propeller 26, it is possible to form a flow of water around the installation point of the outside propeller 26.

In addition, a screw blade 21 is installed in a part of the flow path pipe 130 or branch pipe 140, but the screw blade 21 itself rotates according to the flow of water inside the pipe. 21) may be configured to rotate by receiving the outside propeller 26.

The power transmission unit 27 for transmitting the rotational motion of the propeller 25 or the screw blade 21 in the pipe to the propeller 26 outside the pipe selectively selects a known gear structure, a spiral shaft structure, a chain structure, a flexible structure, etc. It can be applied, and two or more of the listed structures may be applied in combination, as well as any type of power transmission structure for transmitting rotational motion to other rotational motions.

The out-of-pipe propeller 26 is installed in a direction orthogonal to the pipe direction to induce the flow of water in a direction orthogonal to the flow of water in the pipe, and induces the flow of water to the thickened layer and the upper layer of the river in consideration of the flow state of water. Can be installed to do.

In the present invention, a separate support 28 for installing the propeller 26 outside the pipe, a pipe fixing device 29 for preventing shaking of the flow path pipe 130 or branch pipe 140 may be additionally configured. .

In addition, one or a plurality of air inlet pipes 70 may be communicated around the outlet 10 of the flow path pipe 130 as shown in FIG. 14. A negative pressure is formed in the inside of the pipe around the outlet 10 of the flow pipe 130 by the flow rate of water. Accordingly, air is introduced into the flow path pipe 130 through the air inlet pipe 70 and is discharged in a mixed state with water. Particularly, as shown in (a) of [Fig. 14], the air inlet pipe 70 communicates in a diagonal direction so as to face the outlet 10, thereby inducing smoother air inflow. In addition, as shown in (b) and (c) of [Fig. 14], the air introduced by forming regular or irregular teeth, protruding jaws, etc. in the outlet portion 72 of the air inlet pipe 70 , It is dispersed by a protruding jaw to increase the effect of mixing air with water, and accordingly, when the water upstream of the river is discharged through the discharge port 10, water with a large amount of dissolved oxygen is discharged. Water quality can be improved. Chemicals or bubbles for improving water quality may be artificially injected into the air inlet pipe 70. In addition, a strainer for preventing insects from entering may be installed at the inlet portion 71 of the air inlet pipe, if necessary, and an opening/closing valve for preventing reverse flow of water may be additionally coupled to the air inlet pipe 70 .

In addition, a purification tank 190 may be installed in the concave portion 120 to discharge water after purification treatment of the water discharged from the outlet 10 as shown in FIG. 15. The system 100 of the present invention uses a siphon principle to circulate water while discharging water and sludge from the compensation stream to the downstream, but it is also significant in separating and discharging the water in a specific section with high contamination in the compensation stream before diffusion. There is. Although natural purification is carried out in the process of separating and discharging water with high pollution degree, as described above, by installing the purification tank 190 in the concave portion 120, the water separated and discharged from the compensation stream is After the purification process in the purification tank 190, it is discharged to the downstream side.

The purification tank 190 may also be configured in various ways, but as shown in [Fig. 14], the interior is composed of a plurality of layers, so that the water discharged through the discharge port 10 is purged in the process of filling up from the lowermost layer to the uppermost layer. You can adopt the way in which this is done.

The present invention has been described in connection with a preferred embodiment as mentioned above, but various modifications and variations can be made without departing from the gist of the present invention, and can be used in various fields.
